3 Auras of choice perma turned on and thats it

Jokes aside and in Easy words: '3 Auras at once. Toggle one off, click another one and get 4.5 sec cd on ALL auras with that.' Thats how you plan it right?
How about instead of having to toggle off one of the Auras, just remove the _first_ one cast in the 'rotation' and replace it with the new one when you click on an Aura? Like i got Str(1)+Toug(2)+Resis(3), i press on Dmg reflec Aura, and then i have the new 3 ones Toug(1)+Resis(2)+Reflec(3), while getting my 5 sec CD on all other auras. I guess that would resemble current system the closest (allthough i find this one a lil tooooo easy going, the toggle on-off would be imo better)
